Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the pins of the electronic component are moved to the top position of the light source and moved down to approach the light source for image capture, then the illumination and image quality improve, but the process complexity and time consumption increase, reducing insertion efficiency

Engineering Contradiction:

Improvepin position recognition accuracyVSAvoidinsertion efficiency

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

Instead of moving the electronic component pins down to approach the light source from above, the patent inverts the approach by placing the light source below the pins and moving the component horizontally to position the pins over the light source. This eliminates the vertical movement step while achieving the same illumination effect.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent changes the dimensional approach from vertical movement (moving pins down to light source) to horizontal movement (moving component horizontally to position pins over light source). This dimensional shift simplifies the positioning process while maintaining effective illumination.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Measurement precision

If the electronic component is moved vertically to position the pins at the top of the light source, then the image capture quality improves, but the process time and operational complexity increase

Engineering Contradiction:

Improvepin image qualityVSAvoidtime for positioning and image capture

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent inverts the traditional vertical positioning approach by using horizontal movement to achieve the same imaging goal. The component is moved horizontally to position the pins over the light source rather than moving the pins vertically down to the light source, significantly reducing positioning time.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent extracts the vertical movement step from the positioning process, eliminating the need to move the component vertically to position pins at the top of the light source. Only horizontal movement is required, which simplifies the process and reduces time loss.

Inventive Principle:

Principle #2Taking out (Extraction)

3Adaptability or versatility

If manual operators perform the insertion process, then flexibility and adaptability are maintained, but manpower consumption increases and errors such as incorrect insertion and missing parts occur

Engineering Contradiction:

Improvehandling flexibilityVSAvoidinsertion accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent replaces the manual mechanical insertion process with an automated system that uses optical illumination and image capture to guide the insertion. The automated lighting and positioning system eliminates human error while maintaining the ability to handle various component types through programmable control.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
